Definitions

  • the present invention is directed to a tool holder for securing a tool in a hammer drill.
  • Locking elements are radially adjustably supported in a guide member for at least partial engagement within closed end recesses in the tool shank.
  • An adjustment ring is rotatably mounted on the guide member and adjusts the position of the locking elements in the radial direction.
  • An axially slidable fixing sleeve is positioned on the guide member and can be engaged in a form-locking member with the adjustment ring preventing rotation of the adjustment ring relative to the guide member.
  • the locking elements are supported in a guided manner and can be radially engaged or disengaged by a rotatable or slidable adjustment ring. Due to the path determined by the adjustment ring, in known hammer drills there is a uniform depth of the recesses formed in the tool shank. As a consequence, the tool holder can only accept tools of a specific shank diameter. In addition, this disadvantage results in that large differences in diameter occur between the working diameter of the drill and its shank. If the shank is designed for tools with a smaller diameter, then it is too weak for larger tools. If the shank is designed for tools with a larger diameter, however, then the smaller tools are very complicated concerning their material content as well as the cutting or non-cutting shaping of the tool so that economical manufacture of such tools is not possible.
  • the adjustment ring for the locking elements can be locked in at least two positions by the fixing sleeve for each full turn or revolution of the adjustment ring relative to the guide member.
  • the fixing sleeve for each full turn of the adjustment ring, there are at least two positions of the locking elements for centering the tool.
  • For the intended range of adjustment of the locking element usually several turns of the adjustment ring are needed. This results in a plurality of fixing positions of the locking elements which are uniformly distributed over the entire adjustment ring.
  • one or a number of spring elements can be provided for biasing the fixing sleeve into the locking position.
  • spring elements it is also possible to provide a stop device for securing the fixing sleeve in the locking position.
  • the toothed construction or the counter toothed construction may, for instance, be in the form of an axially engaging frontal toothed arrangement.
  • vibrations are developed such that due to axial sliding of the fixing sleeve, the inter-engaged toothed constructions may become disengaged.
  • the shape of the toothed construction may be selected as desired with regard to its function, for manufacturing reasons, however, it is advantageous when the toothed construction and the counter toothed construction are formed as a serrated connection. Since the mechanical stress on the toothed constructions is relatively minor, the serrations may be produced in a milling operation. With a serrated connection, it is possible to provide a plurality of positions affording mutual engagement between the two members and consequently a fine gradation of the fixable positions of the locking elements. For instance, a specific radial play between the locking elements and the tool shank can be set.
  • the fixing sleeve is secured with the guide member so that there is no relative rotation between them. Consequently, the adjustment ring must be rotated relative to the fixing sleeve for adjusting the locking elements.
  • the fixing sleeve, secured to rotate with the guide member can serve during adjustment of the tool holder as an abutment. Accordingly, an operator can hold the fixing sleeve with one hand and the adjustment ring with the other.
  • the counter toothed construction is located on the adjustment ring.
  • FIG. 1 is an axially extending sectional view of a tool holder embodying the present invention with a tool inserted in the locked position;
  • FIG. 2 is a cross sectional view taken along the line II--II in FIG. 1
  • FIG. 3 is a cross sectional view taken along the line III--III in FIG. 1;
  • FIG. 4 is a view of the tool holder similar to that shown in FIG. 1, however, the tool holder is in the unlocked position.
  • the tool holder illustrated in FIGS. 1-4 is used with a hammer drill where both rotational and impact forces are transmitted to a tool secured in the tool holder.
  • the front end of the tool holder is its left hand end into which the tool is inserted and the right hand end is its rear end.
  • the tool holder includes an axially extended guide member 1 with its axial direction extending in the front end-rear end direction of the holder. Axially extending the slots 1a are located in the front end of the guide member and are open in the radial direction with locking elements 2 radially slidable in the slots.
  • An adjustment ring 3 coaxial with the guide member is screwed onto the axially extending thread 1b on the outer surface of the guide member.
  • locking elements 2 are biased by an annular spring 4 against the frusto-conically shaped inside surface 3a of the adjustment ring 3.
  • the inside surface 3a of the adjustment ring widens from the front end toward the rear end of the tool holder.
  • the locking elements are moved radially inwardly or outwardly.
  • the guide member 1 is connected by a pin 5 to an anvil 6 with the connection permitting the transfer of both rotary and impacting motion.
  • the anvil 6 has arcuately shaped recesses 6a which are somewhat longer in the axial direction of the tool holder than the diameter of the bolt 5 so that the anvil 6 and the guide member 1 are secured together for rotation, however, there is a specific axial play between the two. This axial play is needed for the direct transfer of the impacting force to a tool 10 inserted into the tool holder.
  • the shank of the tool 10 inserted into the tool holder has axially closed or closed end recesses 10a and these recesses are longer in the axial direction of the tool holder than the locking elements, note FIG. 1, whereby the tool 10 is axially movable to a limited extent relative to the locking elements.
  • the guide member 1 is laterally enclosed by a fixing sleeve 7.
  • the fixing sleeve 7 has an axially extending slot 7a with a pin 8 seated within a radially extending blind bore in the guide member 1 and projecting outwardly into the slot 7a.
  • the interconnection of the pin 8 with the slot 7a secures the fixing sleeve 7 to the guide member 1 so that they rotate together, however, a certain axial sliding movement is provided for the fixing sleeve relative to the guide member.
  • the front end of the fixing sleeve 7 facing toward the rear end of the adjustment ring 3 is provided with axially extending serrations 7b on its radially outwardly facing surface.
  • the front end of the fixing sleeve 7 is stepped in-wardly relative to the remainder of its outside diameter and to the outside diameter of the adjustment ring.
  • its inside surface is stepped outwardly and an inner serration 3b is formed in this outwardly stepped surface. Accordingly, in the locked position, the front end of the fixing sleeve 7 telescopically engages within the rear end of the adjustment ring 3 in a form-locking manner.
  • Fixing sleeve 7 is biased into locking engagement with the adjustment ring 3 by a compression spring 9.
  • annular spring 4 biases the locking elements against the frusto-conically shaped inside surface of the adjustment ring 3. Accordingly, as the frusto-conically shaped inside surface 3a moves relative to the locking elements 2 and depending on its direction of movement, the locking elements are moved radially inwardly or outwardly.
  • FIG. 3 the form-locking engagement of the outer serration 7b of the fixing sleeve 7 with the inner serration 3b of the adjustment ring 3 is illustrated. During its sliding movement in the axial direction, fixing sleeve 7 is guided on the surface of the guide member 1.
  • the adjustment ring 3 has been moved in the axial direction forwardly relative to the guide member 1 and, as a consequence, the locking elements 2 under the biasing action of the spring 4 have been displaced radially outwardly into their outermost position and the tool 10, shown in FIG. 1, has been removed.
  • the fixing sleeve 7 has previously been moved in the rearward direction against the biasing action of the spring 9.
  • the locking elements can be moved radially inwardly by displacing the adjustment ring so that the locking elements engage within the closed end recesses 10a in the tool shank.
  • the sleeve is moved forwardly into the locking position in telescopic inter-engagement with the feed ring as shown in FIG. 1.
